Cleaning Natural Stone requires more care than cleaning regular porcelain or ceramic tile and grout. First of all the cleaning products must be suitable for natural stone or the stone can get ruined. Polished marble will definitely display dull spots and etch marks if an unsuitable cleaner is used. However even honed finish stones like limestone and travertine will look hazy and uneven if cleaned improperly. Furthermore many stones like limestone, travertine and marble are soft and scratch easily. The aggressive scrubbing and stiff brushes used to clean regular tile and grout can possibly scratch and ruin the stones. Experience and expertise are a must when cleaning natural stone. Many times natural stones do not need a cleaning as cleaning would be ineffective or insufficient. Rather the stone needs to be refinished and a complete restoration. Whether a marble shower or travertine foyer floor or a limestone kitchen floor, it will need to be refinished and honed with diamonds periodically.
